MasterFormat Division 35 – Waterway and Marine Construction in the Bidding & Negotiation Phase

Start with [CSI MasterFormat Division 35: Waterway and Marine Construction](/MasterFormat-division-35-waterway-and-marine-construction) for the broad scope and coordination boundaries. This page addresses the narrower bidding & negotiation phase intent.

Division 35 Activities During Bidding & Negotiation

During bidding and negotiation, the specification organization directly determines how trades scope their work. Bid packages organized by MasterFormat divisions align with the project manual, enabling accurate trade scoping, consistent estimates, and comparable bids. Misalignment between bid package organization and specification structure is a primary source of scope gaps and change orders. For Division 35 specifically, the bidding & negotiation phase involves focused work on waterway and marine construction scope, products, and execution requirements. Organize bid packages and scope sheets by MasterFormat divisions/sections to align with the project manual. Ensure all bidders reference the same section numbers and edition.

Key activities for Division 35 during bidding & negotiation include:

• Organize bid packages by MasterFormat divisions/sections — as it relates to waterway and marine construction sections and the products, methods, and quality standards they define
• Ensure bidder scope sheets reference correct specification sections — as it relates to waterway and marine construction sections and the products, methods, and quality standards they define
• Maintain edition consistency across all bid documents — as it relates to waterway and marine construction sections and the products, methods, and quality standards they define

Each of these activities requires current, accurate Division 35 section numbers. When teams reference outdated or incorrect section numbers during bidding & negotiation, the errors propagate into every subsequent phase.

Division 35 Sections Referenced in Bidding & Negotiation

The following Division 35 sections are commonly referenced during bidding & negotiation work:

• 35 20 00 – Waterway and Marine Construction and Equipment
• 35 30 00 – Coastal Construction
• 35 40 00 – Waterway Construction and Equipment
• 35 50 00 – Marine Construction and Equipment
• 35 70 00 – Dam Construction and Equipment

These sections define the scope boundaries, product requirements, and execution standards for waterway and marine construction work. During bidding & negotiation, these section references appear in trade scope sheets aligned with specifications and bid comparison matrices by specification section and must be consistent with the project manual.

Bidding & Negotiation Deliverables That Reference Division 35

Project teams produce or consume these deliverables during the bidding & negotiation phase, many of which directly reference Division 35 sections:

• Trade scope sheets aligned with specifications
• Bid comparison matrices by specification section
• Scope gap analysis reports

Every deliverable that references Division 35 must use current section numbers and titles. A single incorrect section reference in a bidding & negotiation deliverable can trigger RFIs, scope disputes, or change orders during construction.

Common Issues with Division 35 During Bidding & Negotiation

• Bid packages organized differently than specifications — When this occurs with Division 35 references during bidding & negotiation, the result is rework, coordination failures, or documentation that contradicts the project manual.
• Scope gaps between trades from classification misalignment — When this occurs with Division 35 references during bidding & negotiation, the result is rework, coordination failures, or documentation that contradicts the project manual.
• Bidders referencing different MasterFormat editions — When this occurs with Division 35 references during bidding & negotiation, the result is rework, coordination failures, or documentation that contradicts the project manual.
• Estimates that can't be compared at the section level — When this occurs with Division 35 references during bidding & negotiation, the result is rework, coordination failures, or documentation that contradicts the project manual.

These issues are compounded when Division 35 sections must coordinate with other divisions. This division includes waterway and marine signaling, dredging, dams, levees, ports, harbors, navigation locks, coastal construction, and underwater construction. The more trades and disciplines that touch Division 35 scope during bidding & negotiation, the higher the cost of classification errors.

Cross-Standard Connections for Division 35 in Bidding & Negotiation

UniFormat: Division 35 extends UniFormat into marine and waterway infrastructure—specialized construction entities beyond typical building scope.

OmniClass: OmniClass Table 11 (Construction Entities) classifies marine and waterway facilities as built environment entities.

During the bidding & negotiation phase, these cross-references ensure that Division 35 specifications align with element-level classifications and lifecycle tags. Teams who rely on marine engineers designing port and harbor facilities and coastal engineers designing shoreline protection to maintain these connections manually risk inconsistencies that surface as coordination issues downstream.

How CSI Dynamic Standards Helps with Division 35 in Bidding & Negotiation

CSI Dynamic Standards includes Division 35 as part of a connected, edition-aware classification system—licensed through The Construction Standard. Built for real project work from concept to closeout and beyond, it provides always-current Division 35 section numbers and titles, governed cross-references to UniFormat and OmniClass, and edition tracking that prevents bidding & negotiation deliverables from referencing obsolete classification data. For teams working through the bidding & negotiation phase, this means Division 35 references in every deliverable stay accurate and consistent with the rest of the project manual.
